[0047] To make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the following will be combined with the accompanying drawings for the embodiments of the present disclosure to make a clear and complete description of the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all the embodiments. The components of the embodiments of the present disclosure generally described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed present disclosure, but only represents selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0048] It should be noted that similar reference numerals and letters refer to similar items throughout the accompanying drawings, and therefore, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0049] The term "and / or" herein only describes an associated relationship, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the term "at least one" herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0050] It is found through research that high-speed EMUs, as an important modernized transport tool for transporting passengers, have the characteristics of personnel concentration, space closure, long running line and time, and complex running environment (including tunnels and viaducts). Once a fire occurs, it is a great threat to personnel safety, and rescue forces are difficult to arrive in time. Therefore, it is necessary to develop a scientific and reasonable evacuation strategy. Ensuring that the vehicle has running ability under fire and can run to the designated area is a prerequisite for evacuation. At present, since the research on the running ability of railway vehicles under fire started late in China, the evaluation method for maintaining the running ability of railway vehicles under fire is not comprehensive and systematic, so it is necessary to form a systematic evaluation scheme to ensure that the vehicle has a certain running ability under fire, improve the fire safety level of high-speed trains, and protect passenger safety.

[0051] Based on the above research, the present disclosure provides a method and device for evaluating the fire operation maintaining capability of a high-speed train. By obtaining a train operation simulation model, a simulation ignition source corresponding to a preset fire type is applied to a system function block to be evaluated to generate a fire event. The temperature-time curve corresponding to the fire event is input into a preset simulation analysis model to determine whether the system function block to be evaluated can maintain the corresponding operation capability within a preset fire resistance index time. If the system function block to be evaluated cannot maintain the corresponding operation capability, it is determined whether the system function block to be evaluated has a redundant configuration. If there is no redundant configuration, it is determined whether the train is equipped with a fire extinguishing system. If the train is not equipped with the fire extinguishing system, the train is set to run in a degraded mode, and it is determined whether the train traction force can maintain normal driving on a preset line during the running process. If the train traction force cannot maintain the normal operation of the train, it is determined that the system function block to be evaluated does not have the fire operation maintaining capability. The method can comprehensively and efficiently evaluate the capability of each system of a high-speed train to maintain the related functions that should be implemented when a fire occurs, thereby realizing precise monitoring of the fireproof capability of the high-speed train and improving the fireproof safety performance of the high-speed train.

[0052] To facilitate the understanding of the present embodiment, first, a method for evaluating the fire operation maintaining capability of a high-speed train is described in detail. The execution subject of the method for evaluating the fire operation maintaining capability of a high-speed train provided by the present embodiment is generally a computer device with certain computing capability, which may, for example, include a terminal device or a server or other processing device. The terminal device may, for example, be a user equipment (UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. In some possible implementation manners, the method for evaluating the fire operation maintaining capability of a high-speed train may be realized by a processor calling computer readable instructions stored in a memory.

[0053] Referring to FIG. 1, a flowchart of a method for evaluating the fire operation maintaining capability of a high-speed train provided by the present embodiment is shown. The method includes steps S101-S106.

[0054] S101, a train operation simulation model is obtained, and a simulation ignition source corresponding to a preset fire type is applied to a system function block to be evaluated to generate a fire event.

[0055] In a specific implementation, first, a train operation simulation model simulating a train operation state is acquired, a preset fire type determined according to a fire operation retention capability requirement is applied to a system function block to be evaluated included in the train operation simulation model, and a corresponding simulation fire source is applied to simulate a fire event occurring in a high-speed train during operation.

[0056] Here, the system function block included in the train operation simulation model includes various functional components required for simulating train operation, which may, for example, include a power output function block, a braking function block, an automatic control function block, a state monitoring function block, etc., and may be configured according to actual needs, which is not specifically limited here.

[0057] Among them, the fire event can include a second or third class fire, and the preset fire type may, for example, include a luggage fire, a seat fire, a flammable liquid fire, and a new energy battery fire.

[0058] Specifically, the simulation ignition source corresponding to the preset fire type can be simulated and calculated by using a power model as an ignition model.

[0059] For example, the power model uses an ignition source with a nominal radiation flux of 20kWm-2 to 25kWm-2 applied to an area of 0.7m2, with an average output power of 75kW for 2min, and then immediately uses an ignition source with a nominal radiation flux of 40kWm-2 to 50kWm-2 applied to the same 0.7m2 area, with an average output power of 150kW for 8min.

[0060] It should be noted that in the process of evaluating the fire operation retention capability of the high-speed train, the train operation simulation model needs to be first set to a normal operation state, and the fire event caused by the simulation ignition source should be an independent event in the embodiments of the present application, and two or more independent fire events occurring simultaneously are not within the evaluation range of the embodiments of the present application.

[0061] Meanwhile, the evaluation requirements of the high-speed train fire operation retention capability in the embodiments of the present application can include that the on-board battery should be able to provide sufficient power for at least 15 minutes for all battery-required auxiliary equipment; any fire extinguishing system should not affect the unaffected system functions related to the operation capability, and should not cause other ignition events when activated.

[0062] S102, input the temperature-time curve corresponding to the fire event into a preset simulation analysis model to determine whether the to-be-evaluated system function block maintains the corresponding operation capability within the preset fireproof index time.

[0063] In a specific implementation, after a specific type of fire event is tried for the system function block to be evaluated, it is necessary to verify whether the system function has a certain carrying capacity for fire, and the verification can be verified by test verification or conformity assessment verification.

[0064] Referring to FIG. 2, a flowchart of a test method for determining whether a system function block to be evaluated maintains corresponding running capability is provided, and the method includes steps S1021-S1023, wherein:

[0065] S1021, for the cable associated with the running capability of the system function block to be evaluated, test according to EN50200 standard, EN50362 standard or IEC60331-3 standard to determine whether the fire integrity requirement within the preset time range is met.

[0066] S1022, for the technical cabinet associated with the running capability of the system function block to be evaluated, test according to GB-T9978.4 standard to determine whether the fire integrity requirement and the heat insulation requirement of the cabinet surface affected by the fire within the preset time range are met.

[0067] S1023, for the pneumatic and hydraulic equipment associated with the running capability of the system function block to be evaluated, test according to ISO15540 standard to determine whether the fire integrity requirement within the preset time range is met.

[0068] Further, for the evaluation method for determining whether the system function block to be evaluated maintains the corresponding running capability, the preset simulation analysis model can be used for simulation analysis according to the temperature-time corresponding curve of the specific type of fire event, and it is proved that the fire event does not cause the loss of system function within the time of the accident.

[0069] Here, the preset simulation analysis model can use existing professional fireproof simulation analysis software, which can be selected according to actual needs, and is not limited here.

[0070] As a possible implementation, after determining whether the system function block to be evaluated maintains the corresponding running capability within the preset fireproof index time, if the system function block to be evaluated can maintain the corresponding running capability, it is determined that the system function block to be evaluated has fire running retention capability.

[0071] S103, if the system function block to be evaluated cannot maintain the corresponding running capability, it is determined whether the system function block to be evaluated has redundant configuration.

[0072] In a specific implementation, if the system function block to be evaluated cannot maintain the corresponding operating capacity in a fire event, it is necessary to continue to determine whether the system function block to be evaluated has a redundant configuration. To determine whether the system function will be affected by a specific type of fire event, it is necessary to verify whether the system function has a redundant system configuration, which can be verified by a test verification or a compliance evaluation verification.

[0073] Here, when determining the compliance of the system configuration redundancy, the following two points should be considered: first, each way of maintaining the system function is independent; second, at least one method of maintaining the system function continues to function under the influence of a Class 2 fire.

[0074] Specifically, for the compliance test verification of the redundant configuration, the replacement burner standard specified in the 2.2 standard of ISO / TR9705-2:200 can be used in a test facility that meets the actual installation conditions to test and demonstrate the redundant configuration to determine whether the system function block to be evaluated has a redundant configuration.

[0075] Further, for the compliance evaluation verification of the redundant configuration, the temperature-time corresponding curve of a Class 2 fire can be selected to evaluate the system function that may affect the operating capacity, thereby proving that the system function will not be lost during a fire incident.

[0076] As a possible implementation, after determining whether the system function block to be evaluated has a redundant configuration, if the system function block to be evaluated has a redundant configuration, it is determined that the system function block to be evaluated has a fire operation maintaining capability.

[0077] S104, if the redundant configuration does not exist, it is determined whether the train is equipped with a fire extinguishing system.

[0078] In a specific implementation, if the system function block to be evaluated does not have a redundant configuration, it is necessary to continue to determine whether the current train is equipped with a fire extinguishing system.

[0079] Here, the fire extinguishing system should include a fire detection system and a fire extinguishing system, and the fire detection system can be verified by a compliance test or a compliance evaluation, and the fire extinguishing system can only be verified by a compliance test.

[0080] As a possible implementation, after determining whether the train is equipped with a fire extinguishing system, if the train is equipped with a fire extinguishing system, it is determined that the system function block to be evaluated has a fire operation maintaining capability.

[0081] S105, if the fire extinguishing system is not equipped, the train is set to run in a degraded mode, and it is determined whether the train traction can maintain normal driving on the preset line during operation.

[0082] In a specific implementation, if the train is not equipped with a fire-fighting system, the train is set to run in a degraded mode in the train operation simulation model, and during the degraded mode operation of the train, it is determined whether the train can run on a specific route under the influence of a fire event.

[0083] Here, when the running capability maintenance determination, the redundancy configuration determination, and the fire-fighting system determination do not meet the evaluation requirements during the evaluation process of the running capability, it is necessary to determine whether the train can run on a route for which traction calculation has been performed and which meets the operation compliance requirements in a degraded operation mode in which the relevant system functions are in a failure state caused by a fire event.

[0084] Among them, the degraded mode of the train is a mode in which the train is manually switched to a next level of train control mode and maintained in operation when the train cannot maintain normal operation in the current level of train control mode.

[0085] Specifically, in the train operation simulation model, the train is configured to run in a degraded mode; a simulated basic track route meeting the preset traction requirement is constructed as the preset route; and the train operation simulation model is loaded in the simulated basic track route for simulation to determine whether the train traction can maintain normal driving on the preset route during operation.

[0086] As a possible implementation, after determining whether the train traction can maintain normal driving on the preset route during operation, if the train traction can maintain normal operation of the train, it is determined that the system function block to be evaluated has fire operation maintenance capability.

[0087] S106, if the train traction cannot maintain normal operation of the train, it is determined that the system function block to be evaluated does not have fire operation maintenance capability.

[0088] In a specific implementation, when the running capability maintenance determination, the redundancy configuration determination, the fire-fighting system determination, and the degraded operation determination do not meet the evaluation requirements during the above-mentioned evaluation process of the running capability, it is determined that the system function block to be evaluated does not have fire operation maintenance capability, and the design of the fire operation maintenance capability needs to be re-performed.

[0089] The method for evaluating the fire operation maintaining capability of a high-speed train provided in the embodiments of the present disclosure comprises the following steps: obtaining a train operation simulation model, applying a simulation ignition source corresponding to a preset fire type to a system function block to be evaluated to generate a fire event; inputting a temperature-time curve corresponding to the fire event into a preset simulation analysis model to determine whether the system function block to be evaluated can maintain corresponding operation capability within a preset fireproof index time; if the system function block to be evaluated cannot maintain the corresponding operation capability, determining whether the system function block to be evaluated has a redundant configuration; if the redundant configuration does not exist, determining whether the train is equipped with a fire extinguishing system; if the train is not equipped with the fire extinguishing system, setting the train to run in a degraded mode, and determining whether the train traction force can be maintained for normal driving on a preset line during the running process; and if the train traction force cannot maintain the normal operation of the train, determining that the system function block to be evaluated does not have the fire operation maintaining capability. The method can comprehensively and efficiently evaluate the capability of each system of the high-speed train to maintain the related functions that should be implemented when a fire occurs, thereby realizing accurate monitoring of the fireproof capability of the high-speed train and improving the fireproof safety performance of the high-speed train.

[0090] Those skilled in the art can understand that, in the above method of the specific implementation, the writing order of each step does not mean a strict execution order and does not constitute any limitation on the implementation process, and the specific execution order of each step should be determined according to its function and possible internal logic.
